NHA Certified Phlebotomy Technician (CPT)Safety and ComplianceMedium
A phlebotomy technician is asked to label blood collection tubes. According to CLSI guidelines, when should the labels be applied?
- ABefore drawing the blood, at the phlebotomy station.
- BAfter transporting the specimens to the laboratory.
- CImmediately after drawing the blood, at the patient's bedside.
- DOnce all specimens from a round of collections have been gathered.
Show answer & explanationAnswer & explanation
Correct answer: C. Immediately after drawing the blood, at the patient's bedside.
CLSI (Clinical and Laboratory Standards Institute) guidelines mandate that blood collection tubes must be labeled immediately after collection and before leaving the patient's side. This critical step prevents mislabeling and ensures accurate patient identification for each specimen.
Why the other options are wrong
- A. Pre-labeling risks using the wrong label for the wrong patient or specimen.
- B. Labeling in the lab risks specimens being unlabeled or mislabeled during transport or before reaching the lab.
- D. Batch labeling significantly increases the risk of specimen misidentification, a serious safety error.
Specimen Labeling Timing
The critical timeframe for labeling blood collection tubes to ensure accurate patient identification and prevent medical errors.
- Labeling must occur immediately after collection.
- Labeling must occur at the patient's bedside/chair.
- Patient's identity must be verified against the label.
- Labels must include patient name, DOB, collection date/time, phlebotomist ID.
Memory trick: Label IT: Immediately, Together, at bedside.
